From the question, we are informed that Brianna teacher gives her a container that has 0.25 liter of a liquid in it and she needs to use 0.4 of this liquid for the experiment.
The amount of liquid that Brianna will use will be:
So the equation is parallel and the slope will be 2 y=0.6x+b sub in(-2,2) for x and y to find b 2=0.6(-2)+b 2+1.2=b b=3.2 therefore the equation is y=0.6x+3.2
